SPARK-ARRESTER.

SPEGIFIGATION forming part of Letters Patent No. 553,079, dated January14, 1896. Application filed July 30, 1895. Serial No. 557,604. (Nomodel.)

To all whom, it may concern:

Be it known that I, EDGAR J. SOLOMON, of Carlinville, in the county ofMacoupin and State of Illinois, have invented a new and ImprovedSparlelkrrester, of which the following is a full, clear, and exactdescription.

The object of my invention is to provide a simple and eihcient devicefor attachment to a locomotive, for preventing the escape to thesmoke-stack of sparks and cinders, while permitting of the free escapeof the products of combustion.

The invention consists in the construction hereinafter described andclaimed.

Reference is to be had to the accompanying drawings, forming apart ofthis specification,

in which similar characters of reference indicate corresponding parts inboth the views.

Figure 1 is a sectional end elevation of a locomotive-boiler, showingthe application of my improvement; andFigfiQ is a longitudinal sectionof the attachment,

The locomotive-boiler A is provided with a smoke-box B,eXhaust-nozzle-O,- and smokestack D of usual description. To theexhaustnozzle Gis fitted the lower end of the tube E,

which in the present case is conical in form.

The tube E may be secured to the nozzle in any convenient way. Ihaveshown a simple and practical device for this purpose, which consistsof a ring a fitted to the tube, and setscrews b passing through the ringand the tube and bearing upon the sides of the exhaust-nozzle. The upperand large end of the tube E fits into thelower end of the smokestack D,and in the sides of the tube E are made U-shaped slits c, leaving atongue of metal cl, which in each case is pressed inwardly, as shown inFig. 2, thereby leaving sufficient space between the tongue and the wallof the tube for the escape of the products of combustion. The slits care in all sides of the tube E, and the combined area of all of theopenings made by pressing in the tongues cl is sufficient for the readyescape of all the products of combustion.

The exhaust in passing through the tube E creates a draft in thewell-known manner and draws all the products of combustion to the tubeE, through which the gaseous portions escape to the smoke-stack, whilethe solid portions, striking the tongues 61, are thrown back into thesmoke-box B, where they remain until the smoke-box is cleaned.

The tube E may be made of any form to adapt itto theparticuiar'locomotive to which my improvement is applied, but theconical form here shown will be found applicable in most cases. It mayalso be made of any suitable material, such as sheet-iron, steel or copper.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A spark arrcster, consisting in a tube having aseries of elongated openings and a tongue projecting downwardly andinwardly from the upper edge of every opening, sub stantially as setforth.

2. A spark arrests-r, comprising a tapering tube formed with a series ofelongated openings and a tongue projecting from the upper edge of everyopening inwardly and downwardly toward the lower smaller end of thetube, substantially as described.
